The Optimal Elastic Flagellum
SaverioIV
311 views
The optimal planar, periodic shape of a swimming slender body at zero Reynolds number. A swimming efficiency is maximized which is a ratio of the work required to drag the ...

Rehinging Bi-Flagellar Locomotion in a Viscous Fluid
SaverioIV
443 views
This is the hydrodynamically optimal bi-flagellar locomotion at zero Reynolds number. At the end of each period shown, the hinge switches from one side to the other, and th...

The Skinny Numerical C. Elegans
SaverioIV
613 views
Solving the boundary integral equations for Stokes flow to model a swimming C. Elegans. This thin body makes for a rather better swimmer than its fat counterpart (see other...

The Fat Numerical C. Elegans
SaverioIV
584 views
Solving the boundary integral equations for Stokes flow to model a swimming C. Elegans. This fat body makes for a remarkably poor swimmer, in contrast to a more slender bod...

Pitching Asymmetry in "Backward" Flapping Locomotion
SaverioIV
163 views
A rigid wing is driven at its leading edge (right). The body rotates due to fluid forces and a restorative torque (spring). The horizontal motion is also set by the fluid f...

Stirring in CFD
SaverioIV
308 views
A body rotates in a fluid, and the vorticity shed from this motion is shown in red (positive) and blue (negative).

Shape Changing in an Oscillating Fluid
SaverioIV
188 views
A body may ratchet upward against gravity by changing shape in an oscillating fluid. Basic mechanism is shown via vorticity shedding, compared to a fixed body (after a ramp...
